Issue Details

I am using a PXIe-5841 VST. When opening the RFmx Soft Front Panel, I encounter the following error:

NationalInstruments.RFmx.InstrMX: -1074135025: IVI: (Hex 0xBFFA000F) Invalid parameter.

Invalid model in DriverSetup string.

specified model: 5841

Error code: -1074135025

 

Additionally, in NI Measurement & Automation Explorer (MAX), my device shows a yellow warning icon and is identified as a generic PCI Data Acquisition and Signal Processing Controller, with the warning: Windows does not have a driver associated with your device. 

How can I resolve this error?

Solution

To resolve this issue, download and install the latest compatible versions of the NI-RFmx, NI-RFSA and NI-RFSG drivers. To check the required driver version for your hardware, refer to its User Manual. For an example, see: PXIe-5841 Driver Support - PXIe-5841 User Manual. 

 

If the issue persists, additional steps may be required. Follow the instructions in this article: Driver Not Compatible or Associated With Device Error in NI MAX and Windows Device Manager.

Additional Information

This error occurs because the Windows Operating System has not correctly associated the physical PXIe-5841 card with the required NI drivers. As a result, the IVI session cannot load the appropriate instrument model string.
